Change is coming to Downton Abbey, as yet another character prepares her exit. Siobhan Finneran, who plays O’Brien, has confirmed that she won’t be back for Season 4.

Good thing there’ll be plenty of other new cast members to fill the gap, including Tom Cullen and Harriet Walter as Crawley family friends; opera star Kiri Te Kanawa as a guest; Julien Ovendon as an aristocrat; Joanne David as a duchess; and Nigel Harman as a valet. Additionally, Shirley MacLaine will reprise her role as Lady Cora’s mother. [Deadline, HitFix]

In his first series regular role, Jeffrey Wright has joined the cast of Boardwalk Empire‘s upcoming fourth season as “Valentin Narcisse, Doctor of Divinity, philanthropist, student of culture and the man who runs Harlem.” He joins Ron Livingston, another new regular who was added last week. Season 4 is shooting now and will air sometime this year. [Deadline]

Fox isn’t procrastinating when it comes to its favorite shows. The network has handed early renewals to freshman series The Following and The Mindy Project, along with New Girl and Raising Hope. In addition, they’re in negotiations for a fifth season of Glee. [Deadline]

There’s less cheerful news for ABC’s The Zero Hour, which has already been cancelled after just three episodes. The series was a bust both critically and commercially, so its demise probably won’t be mourned by many. [Vulture]

Is Jay Leno getting ready to hand over The Tonight Show again? Though NBC’s refusing to confirm anything, insider sources say that the network wants to make the 2013-2014 season Leno’s last on the series, with Late Night host Jimmy Fallon poised to the over in summer 2014. If the rumor turns out to be true, let’s just hope Fallon has better luck than the last guy who transition into that spot. [THR]

The X-Files is getting finally getting a tenth season. There is one major catch however: It comes in the form of a comic book by IDW. The new title will be executive produced by X-Files creator Chris Carter and written by Joe Harris, with art by Michael Walsh and colors by Jordie Bellaire. Here’s a summary of the plot:

In the opening story arc, “Believers,” readers will catch up with Dana Scully and Fox Mulder, living normal lives together under secret identities. However, a visit from an old friend threatens to rip them from suburban anonymity, as they learn that someone is preying upon everyone involved in THE X-FILES.

Entertainment Weekly has an extra-glitzy look this week thanks to Behind the Candelabra, Steven Soderbergh‘s Liberace biopic for HBO. Michael Douglas stars as the flamboyant pianist, and Matt Damon as his much younger lover.

A sleek new trailer for Mad Men‘s sixth season has just arrived… and in typical Mad Men fashion, it reveals almost nothing at all. But at least everyone looks really nice.

Mad Men returns with a two-hour season premiere on April 7. [Deadline]

The new trailer for NBC’s Hannibal doesn’t offer too many plot points, either, but it does a good job of conveying the disturbing and disturbingly witty atmosphere of the series. Be warned that it gets kind of gruesome.

If that first Game of Thrones trailer left you jonesing for more, HBO has now unveiled a longer cut of that trailer that adds about 25 seconds to the runtime. Not too shabby, considering the original version was just 60 seconds long.

We also have a series of stark (no pun intended) character posters for the show’s key figures, which you can flip through in the gallery below.

Breaking Badis an dark, disturbing, heart-pounding thrill ride. The set of Breaking Bad, on the other hand, actually looks like a pretty fun, lighthearted place.

There are very few clues to be found here, but it’s just great to see Bryan Cranston, Dean Norris, Bob Odenkirk, and Aaron Paul back in costume again. The second half of Breaking Bad‘s final season airs this summer on AMC. [via Cinema Blend]
